A cube has a side length `1.2xx10^(-2)m`.Calculate its volume

A

`1.72xx10^(-6) m^(3)`

B

`1.78xx10^(-4) m^(3)`

C

`1.7xx10^(-6) m^(3)`

D

`1.73xx10^(-9) m^(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`v=l^(3)=(1.2xx10^(-2)m)^(3) =1.728 xx10^(-8) m^(-3)`
length (l) has two significant figures, the volume (v) will also have two measurement are maximum. In this case the error in g is minimum.
